Embodiments of the present disclosure relate to the field of communication technology.
Network energy saving has important significance for environmental sustainability, reducing impacts (greenhouse gas emission) on environment and saving operating costs. With the popularity of the 5th generation mobile communication technology (5G) in industries and geographical regions, processing more advanced services and applications requires very high data rates, network deployment becomes denser, and more antennas, greater bandwidths and more frequency bands are used. Impacts of 5G on environment need to be controlled, and new solutions need to be developed to improve network energy saving.
Energy consumption has become an important part of operators' operating costs. According to a report of the Global System for Mobile Communications Association (GSMA), energy costs for mobile networks account for about 23% of operators' total costs. Most of the energy consumption comes from wireless access networks, especially active antenna units (AAUs), data centers and optical fiber transmission account for a smaller share. Power consumption of wireless access may be divided into two parts: a dynamic part is consumed only when data transmission/reception is in progress, and a static part is consumed all the time to maintain necessary operations of a wireless access device, even if the data transmission/reception is not in progress.
It should be noted that the above introduction to the technical background is just to facilitate a clear and complete description of the technical solutions of the present disclosure, and is elaborated to facilitate understanding of persons skilled in the art. It cannot be considered that these technical solutions are known by persons skilled in the art just because these solutions are elaborated in the Background of the present disclosure.
Currently, due to introduction of technologies such as large bandwidth/multi-antenna/multi-channel, energy consumption of a base station is relatively large, which has become one of the most urgent problems to be solved by global operators.
Current Release 18 (R18) phase introduces a network energy-saving issue. Network energy-saving technology may be divided into types such as time domain/frequency domain/spatial domain/energy domain, but in practical applications, it is more likely to use through a combination of two or more types of energy-saving technologies. For example, in the aspect of spatial energy-saving technology, the purpose of energy saving may be achieved by adjusting spatial elements. Spatial elements include a logical antenna port, a transmitting and receiving unit (TXRU), a Tx chain, an array antenna factor, etc. In the aspect of time domain energy-saving technology, energy saving may be achieved via a method of a cell ON/OFF or reducing a common channel/signal transmission; and in the aspect of frequency domain energy-saving technology, energy saving may be achieved via a method such as switching a bandwidth part (BWP). Through the above energy-saving technologies, a network device enters an energy-saving mode (a power-saving mode or a dormant mode). When the network device changes between a normal (regular) mode and the energy-saving mode, terminal related processing is affected, including update of a channel state information (CSI) measurement mode, update of channel state information (CSI) report, update of a channel state information reference signal (CSI-RS) resource, and switching of a bandwidth part (BWP), etc. The above related processing is a basis for the network device to schedule a terminal equipment to receive and transmit data. The above related processing further involves configuring and indicating by the network device to the terminal equipment, and reporting from the terminal equipment to the network device.

It is worth noting that
Current Release 18 (R18) phase introduces a network energy-saving issue. Network energy-saving technology may be divided into types such as time domain/frequency domain/spatial domain/energy domain, but in practical applications, it is more likely to use through a combination of two or more types of energy-saving technologies. For example, in the aspect of spatial energy-saving technology, the purpose of energy saving may be achieved by adjusting spatial elements. Spatial elements include a logical antenna port, a transmitting and receiving unit (TXRU), a Tx chain, an array antenna factor, etc. In the aspect of time domain energy-saving technology, energy saving may be achieved via a method of a cell ON/OFF or reducing common signal transmission; and in the aspect of frequency domain energy-saving technology, energy saving may be achieved via a method such as switching a bandwidth part (BWP). Through the above energy-saving technologies, a network device enters an energy-saving mode (power-saving mode or dormant mode). When the network device changes between a normal (regular) mode and the energy-saving mode, terminal related processing will be affected, including update of a channel state information (CSI) measurement mode, update of channel state information (CSI) report, update of a channel state information reference signal (CSI-RS) resource, and switching of a bandwidth part (BWP), etc. The above related processing is a basis for the network device to schedule a terminal equipment to receive and transmit data. The above related processing further involves configuring and indicating by the network device to the terminal equipment, and reporting from the terminal equipment to the network device.
By taking the spatial energy-saving technology as an example, at least one energy-saving mode or normal (regular) mode may be changed by adjusting the number of spatial elements, and in the process of achieving energy saving by adjusting the number of spatial elements, the terminal equipment may change a CSI measurement mode; in addition, in principle, the number of spatial elements should not be less than the number of CSI-RS ports, otherwise a CSI-RS cannot be configured normally; in the process of achieving energy saving by adjusting the number of spatial elements, when the energy-saving mode is turned on or off, the number of spatial elements may be caused to be less than the number of CSI-RS ports, and thus it is necessary to update CSI-RS time-frequency-space resources.
Therefore, how to make the network device and the terminal equipment adapt to impacts of different modes without ambiguity is a key problem i.e., whether a network energy-saving technology may be applied in actual deployment, which needs to be solved urgently. For at least one of the above problems, embodiments of the present disclosure provide an information indication apparatus and an information reception apparatus and method.
Embodiments of the present disclosure provide an information indication method, which is described from a network device side.
Thus, the terminal equipment may adapt to a changed service mode without ambiguity via the indication information, and accurately determine information such as update of a CSI measurement mode and/or update of CSI report and/or update of a CSI-RS resource and/or switching of a BWP, so as to further efficiently perform subsequent uplink data transmission or downlink data reception with the network device.
In some implementations, the service mode includes a normal mode and/or at least one energy-saving mode.
For example, “at least one energy-saving mode” may include at least one of the following modes: “an energy-saving mode”, “a light energy-saving mode”, “a deep energy-saving mode”, or “an energy-saving transition mode”, etc., the present disclosure does not make limitations in this regard; the above “normal mode” may further be replaced with “a common mode”; the above “energy-saving mode” may further be replaced with “a power-saving mode” or “a sleep mode” or “a dormant mode” or “an OFF mode” and other expressions, the present disclosure does not make limitations in this regard.
In some implementations, the service mode may be changed by changing “a spatial element” or changing “an antenna mode”, for example, by turning off some of “the spatial elements”, a network is changed from “the normal mode” to “the energy-saving mode”.
In some implementations, “the spatial element” includes at least one of the following: a logical antenna port, a transmitting and receiving unit (TXRU), a Tx chain, or an array antenna factor, etc.; in some implementations, “the spatial element” may further be directly replaced with “a power saving mode”; “determine to turn on or off at least some of spatial elements” may further be replaced with “determine to turn on or off an energy-saving mode”; or “determine to turn on or off at least some of spatial elements” may further be replaced with “determine to activate or deactivate an energy-saving mode”.
In some implementations, in terms of time-domain energy-saving technology, energy saving may be achieved via a method for cell ON/OFF or reducing common signal transmission. For example, a network may be changed from “a normal mode” to “an energy-saving mode” by turning off some cells.
In some implementations, in terms of frequency domain energy-saving technology, energy saving may be achieved through a method such as switching a bandwidth part (BWP). For example, “the normal mode” or “the energy-saving mode” is configured with a specific bandwidth part (BWP).
In some implementations, the network device further transmits configuration information to the terminal equipment, wherein the configuration information configures a first timer associated with one of at least one energy-saving mode, wherein the first timer sets an application time of one of the at least one energy-saving mode.
For example, the network device transmits the configuration information via higher-layer signaling, such as RRC signaling, wherein the configuration information indicates an application time of the power-saving mode via the first timer, such as 300 ms.
For example, after reading RRC signaling, the terminal equipment obtains the application time of the energy-saving mode, the network device changes a service mode (for example, from the normal mode to the energy-saving mode) and transmits indication information to the terminal equipment, the terminal equipment performs update of a CSI measurement mode, and/or update of a CSI report, and/or update of a CSI-RS resource, and/or switching of a BWP, and resumes the normal mode after 300 ms, descriptions will be made subsequently by combining with specific content of the indication information.
In some implementations, the network device transmits the indication information via semi-static signaling or dynamic signaling.
For example, if the indication information is transmitted by using RRC signaling, for example a RRC reconfiguration process is used, it is implemented as a millisecond level, too large delay goes against supporting a dynamic energy-saving mode, the dynamic energy-saving mode may be of symbol or slot level (less than millisecond). For another example, under normal circumstances, a CSI-RS resource and CSI measurement of a user do not need to be changed frequently, but in the process of an energy-saving operation, the normal mode and the energy-saving mode is switched frequently, and using an RRC signaling process brings large overhead and causes a waste of system resources. Thus, transmitting the indication information via semi-static signaling or dynamic signaling in the above implementations of the present disclosure may further reduce delay and overhead of signaling, and may support switching of the dynamic energy-saving mode.
In some implementations, the semi-static signaling may be MAC CE signaling; the dynamic signaling may be downlink control information (DCI). For example, the dynamic signaling is DCI, the indication information is carried via the DCI, the DCI may be a new added DCI format for the energy-saving mode, or an existing DCI format may be reused, the present disclosure does not make limitations in this regard. For example, in the case of introducing the new added DCI format, the DCI format may be scrambled by introducing a new Radio Network Temporary Identity (RNTI) such as an ES-RNTI (energy saving-RNTI), or a specific time-frequency resource may further be allocated for this new DCI format, so that the terminal equipment may recognize the DCI, the present disclosure does not make limitations in this regard.
In some implementations, the indication information may be transmitted to the terminal equipment via signaling indicating that a service mode is changed; for example, the terminal equipment may be indicated via the DCI to activate/deactivate “an energy-saving mode”, the indication information may be carried via the DCI; optionally, the indication information and the signaling indicating that a service mode is changed may further be transmitted respectively, the present disclosure does not make limitations in this regard.
In some implementations, the semi-static signaling or the dynamic signaling is group signaling, and the network device transmits indication information to multiple terminal equipments via the group signaling; or, the semi-static signaling or the dynamic signaling is UE-specific signaling, and the network device transmits indication information to a terminal equipment via the UE-specific signaling.
In some implementations, the indication information indicates: update of a CSI measurement mode; and/or, update of a CSI report; and/or, update of a CSI-RS resource; and/or, switching of a BWP. The following text will schematically describe indications of the indication information respectively.
The following text specifically describes how to indicate update of the CSI measurement mode.
For example, “CSI measurement mode” means that the terminal equipment performs “merge processing” or “unmerge processing” on a CSI measurement result; for example, “merge processing” may further be replaced with “merge averaging” or “smooth filtering”; for specific implementations of “merge processing” or “smooth filtering”, related arts may be referred to, the present disclosure does not make limitations in this regard.
For example, in “the normal mode” (“non-power-saving mode”), the terminal equipment generally performs merge processing on all CSI measurement results; however, in a case where “the energy-saving mode” is enabled, transmission power of a channel state indication reference signal (CSI-RS) changes, and the last CSI measurement mode after “the normal mode” is changed to “the energy-saving mode” should also change accordingly to reflect a channel quality state in real time. For example, when “the normal mode” is changed to “the energy-saving mode”, if the terminal equipment still performs merge processing on CSI measurement results, CSI measurement results of “the normal mode” and “the energy-saving mode” may be possibly merged. Thus, a merged CSI measurement result is not able to truly reflect a channel state of the energy-saving mode. Implementations of the present disclosure may enable the terminal equipment timely obtain whether the CSI measurement mode is changed or not via the indication information, and thus CSI measurement may be carried out more accurately.
In some implementations, the network device indicates, via the indication information indicating the update of CSI measurement mode and/or the first timer, whether the CSI measurement mode is changed or not.
In some implementations, in a case where the network device changes the service mode, the indication information indicates, via a value of one or more bits, to change the CSI measurement mode, and/or, indicates, via another value of the one or more bits, not to change the CSI measurement mode.
In some implementations, in a case where the semi-static signaling or the dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks.
For example, each block corresponds to a terminal equipment, and a starting position and/or size of each block is/are configured by high-layer signaling.
For example, each block represents indication information of a terminal equipment, and a starting position and/or size of each block is/are given by a higher-layer parameter, for example, a higher-layer parameter in the existing standard may be used, or a new higher-layer parameter may be introduced, the present disclosure does not make limitations in this regard.
By taking each block being 1 bit as an example, the network device may indicate whether a CSI measurement mode of a specific terminal equipment is changed or not via 1 bit, for example, the bit is “1”, in order to change the CSI measurement mode, it may also be said that CSI measurement merge processing is not performed; the bit is “0”, in order not to change the CSI measurement mode, it may also be said that CSI measurement merge processing is performed.
For example, for five terminal equipments, the meaning of specific content “11010” of the indication information is: for the first, second and fourth terminal equipments, CSI measurement merge processing is not performed; for the third and fifth terminal equipments, CSI measurement merge processing is performed. By taking the third terminal equipment as an example, the indication information obtained by the third terminal equipment via higher-layer signaling is 5 bits in total, wherein a size of each block is 1 bit, thus the third terminal equipment may determine that the third bit (value thereof is “0”) is an indication bit of the third terminal equipment.
In some implementations, if the CSI measurement mode of the terminal equipment is changed, the indication information carries a corresponding block of the terminal equipment; and if the CSI measurement mode of the terminal equipment is not changed, the indication information does not carry the corresponding block of the terminal equipment. For example, if the terminal equipment fails to read relevant fields of the indication information via higher-layer signaling, it is considered that the CSI measurement mode is not changed, and an original CSI measurement mode is still used.
In some implementations, the semi-static signaling or the dynamic signaling is UE-specific signaling. For example, the network device may indicate whether a CSI measurement mode is changed or not via 1 bit, for example, the bit is “1”, in order to change the CSI measurement mode, it may also be said that CSI measurement merge processing is not performed; the bit is “0”, in order not to change the CSI measurement mode, it may also be said that CSI measurement merge processing is performed.
The above bit content is only exemplary description, a bit may further be set to be “0”, in order to change the CSI measurement mode, it may also be said that CSI measurement merge processing is not performed; the bit is “1”, in order not to change the CSI measurement mode, the present disclosure does not make limitations in this regard.
In some implementations, the terminal equipment changes the CSI measurement mode after the first timer expires.
For example, the network device transmits the configuration information via higher-layer signaling, such as RRC signaling, wherein the configuration information indicates an application time of the power-saving mode. For example, after reading RRC signaling, the terminal equipment obtains the application time of the energy-saving mode, the network device changes a service mode (for example, from the normal mode to the energy-saving mode) and transmits indication information to the terminal equipment (using said indication method), the terminal equipment performs update of a CSI measurement mode, for example does not perform merge processing when the normal mode is changed to the energy-save mode, and resumes the normal mode after 300 ms, and changes the CSI measurement mode, for example does not perform merge processing on CSI measurements when 300 ms expires.
Thus, the terminal equipment may obtain specific content of the indication information, and may perform CSI measurements more accurately.
The following text specifically describes how to indicate update of the CSI report.
In some implementations, the network device activates/deactivates, via the indication information indicating the update of CSI report and/or the first timer, at least one CSI report.
In some implementations, in a case where the network device changes a service mode, the indication information indicates to activate first CSI report and/or deactivate second CSI report, wherein the first CSI report and/or the second CSI report is/are configured by higher-layer information.
In some implementations, the first CSI report and/or the second CSI report belong(s) to a first CSI report list which includes a CSI report configuration index (CSI-ReportConfigId), wherein the first CSI report list and the CSI report configuration index (CSI-ReportConfigId) are configured by higher-layer information.
For example, each CSI report corresponds to a CSI report configuration index (CSI-ReportConfigId), for example, CSI report corresponding to a CSI report configuration index (CSI-ReportConfigId)=0 is: CSI 0.
For example, the first CSI report list contains which CSI reports are configured by higher-layer signaling. For example, the higher-layer signaling configures the first CSI report list to contain five CSI reports, corresponding to “CSI 0” to “CSI 4” respectively; the terminal equipment determines to activate/deactivate which specific CSI report according to the indication information. The Specification will illustrate with examples in the subsequent contents by further combining with implementations.
In some implementations, wherein the CSI report configuration index (CSI-ReportConfigId) included in the first CSI report list is associated with a change of at least one piece of the following information:
For example, the CSI report period may be longer in the energy-saving mode. For example, the CSI report period is 40 ms in the normal mode and 80 ms in the energy-saving mode. For example, a higher layer configures a period of CSI 0 to be 80 ms and a period of CSI 1 to be 40 ms, and the first CSI report list includes CSI 0 and CSI 1, and after the service mode is changed to the energy-saving mode, the indication information may indicate to activate CSI 0 (first CSI report) and deactivate CSI 1 (second CSI report). The Specification will illustrate with examples in the subsequent contents by further combining with implementations.
For another example, the CSI-RS resource to which the CSI report is bound in the energy-saving mode is CSI-RS 16 port, the CSI-RS resource to which the CSI report is bound in the normal mode is CSI-RS 32 port, for example a higher layer configures CSI 0 to be bound to CSI-RS 0 of 32 ports and CSI 1 to be bound to CSI-RS 1 of 16 ports, and the first CSI report list includes CSI 0 and CSI 1, and after the service mode is changed to the energy-saving mode, the indication information may indicate to activate CSI 1 (first CSI report) and deactivate CSI 0 (second CSI report), activating CSI 1 also means activating CSI-RS 1 of 16 ports to which it is bound, and deactivating CSI 0 also means deactivating CSI-RS 0 of 32 ports to which it is bound.
In some implementations, for a specific CSI report, the indication information indicates, via a value of one or more bits, to activate the CSI report, and indicates, via another value of the one or more bits, to deactivate the CSI report.
In some implementations, in a case where the semi-static signaling or the dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks, wherein each block corresponds to a terminal equipment, and a starting position and/or size of each block is/are configured by high-layer signaling, each block includes one or more bits, each block indicates the first CSI report list of a terminal equipment, and each bit in each block corresponds to CSI report in the first CSI report list.
For example, still by taking the bitmap of multiple blocks shown in
For example, each block corresponds to a first CSI report list of a specific terminal equipment, each block e.g. includes X bits, wherein each of the X bits corresponds to an activation/deactivation state of one CSI report in the first CSI report list, the list may be given by a higher-layer parameter.
By taking a specific terminal equipment as an example, for example a higher-layer parameter configures the first CSI report list to include 5 CSI reports, corresponding to “CSI 0”-“CSI 4” respectively, an activation/deactivation state of each CSI report is indicated via 5 bits, for example “0” represents deactivating CSI report, “1” represents activating CSI report; for example, the higher-layer parameter configures a CSI period of “CSI 0” (first CSI report) to be 80 m and a CSI period of “CSI 1”-“CSI 4” (second CSI report) to be 40 m, “10000” may be transmitted to a user equipment, which means that is to activate “CSI 0” and to deactivate “CSI 1”-“CSI 4”.
For example, for five terminal equipments, the indication information are “10000′ ‘10100’ ‘00011’ ‘00100’ ‘10001’”; by taking a second terminal equipment as an example, the indication information obtained by the second terminal equipment via higher-layer signaling is 25 bits in total, with 6 bits at a starting position, and the size of indication information of the terminal is 5 bits, i.e., the sixth to tenth bits are indication bits of the second terminal equipment, in which ‘10100’ indicates, for the second terminal equipment, activating “CSI 0” (first CSI report) and “CSI 2” (first CSI report), and deactivating “CSI 1” (second CSI report), “CSI 3” (second CSI report) and “CSI 4” (second CSI report). The above is only exemplary description. For example, the first CSI report list may be different for different terminal equipments.
In some implementations, if CSI report activation/deactivation states of the terminal equipment need to be update, the indication information carries a corresponding block of the terminal equipment; and if CSI report activation/deactivation states of the terminal equipment do not need to be updated, the indication information does not carry the corresponding block of the terminal equipment. For example, if the terminal equipment fails to read relevant fields of the indication information via higher-layer signaling, it is considered that CSI report activation/deactivation states do not need to be updated.
The above bit content is only exemplary description, “0” may also be set to represent activating CSI report and “1” to represent deactivating CSI report, the present disclosure does not make limitations in this regard.
In some implementations, the first CSI report and/or the second CSI report include(s): periodic CSI report, semi-persistent CSI report or non-periodic CSI report; for example, for specific contents of periodic CSI report, semi-persistent CSI report or non-periodic CSI report, related arts may be referred to, the present disclosure does not make limitations in this regard.
For example, for a specific terminal equipment, in a case where the terminal equipment is in a normal mode, CSI report configured for it is “CSI 0”, a CSI-RS resource bound to it is “CSI-RS 0”; in a case where the terminal equipment is in an energy-saving mode, CSI report configured for it is “CSI 1”, a CSI-RS resource bound to it is “CSI-RS 1”. For example, by combining with the above method for updating CSI report, in the case of changing a service mode into the energy-saving mode, indication information transmitted by a network device is “ . . . ‘01000’ . . . ”, corresponding updated and activated CSI report is “CSI 1”. For example, in the case of changing the service mode into the normal mode, indication information transmitted is “ . . . ‘10000’ . . . ”, corresponding updated and activated CSI report is “CSI 0”.
In some implementations, the semi-static signaling or the dynamic signaling is UE-specific signaling. For example, the network device may indicate a first CSI report list via X bits; each of the X bit specifically indicates activating CSI report or deactivating CSI report. For example, “1” represents activating CSI report, 0 represents deactivating CSI report. For example, content of each block adopting the above implementations, as specific content of UE-specific signaling, is transmitted to a specific terminal equipment. For a specific indication method, the above implementations may be referred to, repeated description is omitted here.
In some implementations, when a service mode is changed, the terminal equipment starts a first timer and suspends CSI report before the service mode is changed; and after the first timer expires, the terminal equipment resumes the CSI report before the service mode is changed.
For example, the network device transmits the configuration information via higher-layer signaling, such as RRC signaling, wherein the configuration information indicates an application time of the power-saving mode. For example, after reading RRC signaling, the terminal equipment obtains the application time of the energy-saving mode, the network device changes a service mode (for example, from the normal mode to the energy-saving mode) and transmits indication information to the terminal equipment (using said indication method), the terminal equipment updates activated/deactivated CSI report, suspends the activated/deactivated CSI report in the normal mode, and resumes the normal mode after 300 ms, i.e., the first timer expires, and resumes the activated/deactivated CSI report in the normal mode.
Thus, the terminal equipment may obtain specific content of the indication information, and may determine update of CSI report.
The following text specifically describes how to indicate update of a CSI-RS resource.
In some implementations, the network device activates/deactivates, via the indication information indicating the update of a CSI-RS resource and/or the first timer, at least one CSI-RS resource.
In some implementations, in a case where the network device changes a service mode, the indication information indicates to activate a first CSI-RS resource and/or deactivate a second CSI-RS resource, wherein the first CSI-RS resource and/or the second CSI-RS resource is/are configured by higher-layer information, wherein the first CSI-RS resource and/or the second CSI-RS resource is/are the same or different.
In some implementations, the first CSI-RS resource and/or the second CSI-RS resource belong(s) to a first CSI-RS resource set, wherein the first CSI-RS resource set includes CSI-RS resources, and/or CSI-RS ports; wherein an index of the first CSI-RS resource set and the number and indices of the CSI-RS resources included in the first CSI-RS resource set and/or the number and indices of the CSI-RS ports are configured by higher-layer information.
For example, higher-layer signaling configures the first CSI-RS resource set and its index, and the first CSI-RS resource set includes multiple CSI-RS resources and multiple CSI-RS ports and related configurations, wherein for related configurations of multiple CSI-RS resources and multiple CSI-RS ports, related arts may be referred to, the present disclosure does not make limitations in this regard.
The following text takes “the first CSI-RS resource and/or the second CSI-RS resource belong(s) to a first CSI-RS resource set, wherein the first CSI-RS resource set includes CSI-RS resources” as an example.
In some implementations, for a specific CSI-RS resource, the indication information indicates, via a value of one or more bits, to activate the CSI-RS resource, and indicates, via another value of the one or more bits, to deactivate the CSI-RS resource.
In some implementations, the CSI-RS resource includes a group of CSI-RS resources or a CSI-RS resource, the group of CSI-RS resources is configured by higher-layer signaling.
In some implementations, in a case where the semi-static signaling or the dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks; wherein each block corresponds to a terminal equipment, and a starting position and/or size of each block is/are configured by high-layer signaling; each bit corresponds to a group of CSI-RS resources or a CSI-RS resource of the terminal equipment, and the number of the bits is configured by high-layer signaling.
For example, still by taking the bitmap of multiple blocks shown in
For example, each block corresponds to an activation/deactivation state of each CSI-RS resource in a CSI-RS resource set of a specific terminal equipment, for example each block includes X bits, each of the X bits corresponds to the activation/deactivation state of a CSI-RS resource. In some implementations, for specific settings of a CSI-RS resource set and its corresponding CSI-RS resources, related arts may be referred to, the present disclosure does not make limitations in this regard.
For example, the first CSI-RS resource set includes four CSI-RS resources, an activation/deactivation state of each CSI-RS resource is indicated via four bits, for example “0” represents deactivating the CSI-RS resource, “1” represents activating the CSI-RS resource; the meaning of “1010” is activation of “a CSI-RS resource 0” (the first CSI-RS resource), “a CSI-RS resource 2” (the first CSI-RS resource) and deactivation of “a CSI-RS resource 1” (the second CSI-RS resource) and “CSI-RS resource 3” (the second CSI-RS resource).
For example, for two terminal equipments, the indication information is “'1010′ ‘0101’”; by taking a first terminal equipment as an example, the indication information obtained by the first terminal equipment via higher-layer signaling is 8 bits in total, with 1 bit at a starting position, and lasting for 4 bits, i.e., the first to fourth bits are indication bits of the first terminal equipment; in which ‘1010’ indicates, for the first terminal equipment, activating “a CSI-RS resource 0”, “a CSI-RS resource 2” and deactivating “a CSI-RS resource 1” and “a CSI-RS resource 3”.
Optionally, the indication information may further indicate activation/deactivation states of a group of CSI-RS resources, for example “a CSI-RS resource 0” and “a CSI-RS resource 2” are Group 0; “a CSI-RS resource 1” and “a CSI-RS resource 3” are Group 1; for two terminal equipments, indication information is “‘10’ ‘01’”; by taking the first terminal equipment as an example, the indication information obtained by the first terminal equipment via higher-layer signaling is 4 bits in total, in which a size of each block is 2 bits, “a CSI-RS resource 0” and “a CSI-RS resource 2” are Group 0, “a CSI-RS resource 1” and “a CSI-RS resource 3” are Group 1, and the first to second bits are indication bits of the first terminal equipment; in which ‘10’ indicates, for the first terminal equipment, activating “a CSI-RS resource 0”, “a CSI-RS resource 2” and deactivating “a CSI-RS resource 1” and “a CSI-RS resource 3”.
In some implementations, if CSI-RS resource activation/deactivation states of the terminal equipment need to be update, the indication information carries a corresponding block of the terminal equipment; and if CSI-RS resource activation/deactivation states of the terminal equipment do not need to be updated, the indication information does not carry the corresponding block of the terminal equipment. For example, if the terminal equipment fails to read relevant fields of the indication information via higher-layer signaling, it is considered that CSI-RS resource activation/deactivation states do not need to be updated.
The above bit content is only exemplary description, “0” may also be set to represent activating a CSI-RS resource and “1” to represent deactivating the CSI-RS resource, the present disclosure does not make limitations in this regard.
As shown in
In some implementations, the semi-static signaling or the dynamic signaling is UE-specific signaling. For example, the network device may indicate activation/deactivation states of a CSI-RS resource included in a CSI-RS resource set via X bits; each of the X bits indicates activation/deactivation states of a specific CSI-RS resource, for example “1” is activation of a CSI-RS resource; “0” is deactivation of a CSI-RS resource; optionally, the network device may indicate activation/deactivation states of multiple groups of CSI-RS resources included in a CSI-RS resource set via X bits. For example, content of each block adopting the above implementations, as specific content of UE-specific signaling, is transmitted to a specific terminal equipment. For a specific indication method, the above implementations may be referred to, repeated description is omitted here.
In some implementations, after the first timer expires, the terminal equipment suspends a CSI-RS resource before the service mode is changed; and after the first timer expires, the terminal equipment resumes the CSI-RS resource before the service mode is changed.
For example, the network device transmits the configuration information via higher-layer signaling, such as RRC signaling, wherein the configuration information indicates an application time of the power-saving mode. For example, after reading RRC signaling, the terminal equipment obtains the application time of the energy-saving mode, the network device changes a service mode (for example, from the normal mode to the energy-saving mode) and transmits indication information to the terminal equipment (using said indication method), the terminal equipment updates an activated/deactivated CSI-RS resource, suspends the activated/deactivated CSI-RS resource in the normal mode, and resumes the normal mode after 300 ms, i.e., the first timer expires, and resumes the activated/deactivated CSI-RS resource in the normal mode.
Thus, the terminal equipment may obtain specific content of the indication information, and may determine updated activated/deactivated CSI-RS resources.
The following text takes “the first CSI-RS resource and/or the second CSI-RS resource belong(s) to a first CSI-RS resource set, wherein the first CSI-RS resource set includes CSI-RS ports” as an example.
In some implementations, the indication information indicates, via a value of one or more bits, to deactivate the CSI-RS port, and indicates, via another value of the one or more bits, to activate the CSI-RS port.
In some implementations, the CSI-RS port includes a group of CSI-RS ports or one CSI-RS port, the group of CSI-RS ports is configured by higher-layer signaling.
In some implementations, in a case where the semi-static signaling or the dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks, wherein each block corresponds to a terminal equipment, and a starting position and/or size of each block is/are configured by high-layer signaling, wherein each block includes one or more bits, each bit corresponds to a group of CSI-RS ports or one CSI-RS port of the terminal equipment, and the number of the bits is configured by high-layer signaling.
For example, still by taking the bitmap of multiple blocks shown in
For example, each block corresponds to an activation/deactivation state of a CSI-RS port of a specific terminal equipment, for example each block e.g. includes X bits, each of the X bits corresponds to the activation/deactivation state of a CSI-RS port. In some implementations, for specific settings of CSI-RS ports, related arts may be referred to, the present disclosure does not make limitations in this regard.
Optionally, each block may further include information related to CSI-RS resources, for example including T bits (T may be equal to 0), the T bits indicate a CSI-RS resource set and/or CSI-RS resources corresponding to CSI-RS ports, optionally, in the case of T=0, a CSI-RS resource set and/or CSI-RS resources corresponding to CSI-RS ports is/are indicated by higher-layer information.
The description is made below by taking “T=0, i.e., not indicating a CSI-RS resource set and/or CSI-RS resources corresponding to CSI-RS ports” as an example.
For example, a terminal equipment may be configured with 32 CSI-RS ports, activation/deactivation states of a CSI-RS port are indicated via 32 bits, for example “0” represents deactivating the CSI-RS port, “1” represents activating the CSI-RS port; the meaning of “00000000000000001111111111111111” is activation of “CSI-RS port 16”-“CSI-RS port 31” and deactivating of “CSI-RS port 0”-“CSI-RS port 15”; optionally, the indication information may further indicate activation/deactivation states of a group of CSI-RS ports, the group of CSI-RS ports may be one or more CDM groups, for example “CSI-RS port 0”-“CSI-RS port 15” are Group 0; “CSI-RS port 16”-“CSI-RS port 31” are Group 1, or CSI-RS 32 port have four CDM groups in total, “CDM group 0” and “CDM group 1” are Group 0, “CDM group 2” and “CDM group 3” are Group 1.
For example, for two terminal equipments, the indication information is “‘10’ ‘01’”; by taking a first terminal equipment as an example, the indication information obtained by the first terminal equipment via higher-layer signaling is 4 bits in total, a starting position corresponding to the terminal equipment is the first bit, 2 bits in total and “CSI-RS port 0”-“CSI-RS port 15” are Group 0; “CSI-RS port 16”-“CSI-RS port 31” are Group 1, and the first to second bits are indication bits of the first terminal equipment, wherein ‘10’ indicates, for the first terminal equipment, activating “CSI-RS port 0”-“CSI-RS port 15” and deactivating “CSI-RS port 16”-“CSI-RS port 31”.
In addition, for a case that T is not equal to 0, it may be indicated in combination with the above modes of activating/deactivating a CSI-RS port and of activating/deactivating a CSI-RS resource, which is not repeated in the present disclosure.
In some implementations, if activation/deactivation states of a CSI-RS port of the terminal equipment need to be update, the indication information carries a corresponding block of the terminal equipment; and if the CSI-RS port of the terminal equipment does not need to be updated, the indication information does not carry the corresponding block of the terminal equipment. For example, if the terminal equipment fails to read relevant fields of the indication information via higher-layer signaling, it is considered that activation/deactivation states of the CSI-RS port do not need to be updated.
The above bit content is only exemplary description, “0” may also be set to represent activating a CSI-RS port and “1” to represent deactivating a CSI-RS port, the present disclosure does not make limitations in this regard.
As shown in
In some implementations, the semi-static signaling or the dynamic signaling is UE-specific signaling. For example, the network device may indicate activation/deactivation states of a CSI-RS port via X bits; each of the X bits indicates activation/deactivation states of a specific CSI-RS port, for example “1” is activation of a CSI-RS port; “0” is deactivation of a CSI-RS port; optionally, the network device may indicate activation/deactivation states of multiple groups of CSI-RS ports via X bits. For example, content of each block adopting the above implementations, as specific content of UE-specific signaling, is transmitted to a specific terminal equipment. For a specific indication method, the above implementations may be referred to, repeated description is omitted here.
In some implementations, after the first timer expires, the terminal equipment suspends a CSI-RS port before the service mode is changed; and after the first timer expires, the terminal equipment resumes the CSI-RS port before the service mode is changed.
For example, the network device transmits the configuration information via higher-layer signaling, such as RRC signaling, wherein the configuration information indicates an application time of the power-saving mode. For example, after reading RRC signaling, the terminal equipment obtains the application time of the energy-saving mode, the network device changes a service mode (for example, from the normal mode to the energy-saving mode) and transmits indication information to the terminal equipment (using said indication method), the terminal equipment updates an activated/deactivated CSI-RS port, suspends the activated/deactivated CSI-RS port in the normal mode, and resumes the normal mode after 300 ms, i.e., the first timer expires, and resumes the activated/deactivated CSI-RS port in the normal mode.
Thus, the terminal equipment may obtain specific content of the indication information, and may determine updated activated/deactivated CSI-RS ports.
The following text specifically describes how to indicate switching of a BWP.
In some implementations, the network device indicates, via the indication information indicating switching of a BWP and/or the first timer, a BWP after a service mode is changed.
In some implementations, in a case where the network device changes a service mode, the indication information indicates a BWP index after the service mode is changed, wherein the BWP index is configured by higher-layer information.
In some implementations, the BWP index is associated with a CSI report configuration index (CSI-ReportConfigId), wherein the CSI report configuration index (CSI-ReportConfigId) with which the BWP index is associated is configured by higher-layer information.
In some implementations, in a case where the network device changes the service mode, it is switched to activating a BWP to which the BWP index after the service mode is changed corresponds, and at the same time, activating CSI report associated with the associated CSI report configuration index (CSI-ReportConfigId) and deactivating CSI report associated with the CSI report configuration index (CSI-ReportConfigId) with which the BWP index before the service mode is changed is associated.
In some implementations, in a case where the semi-static signaling or the dynamic signaling is group signaling, the indication information is a bitmap including multiple blocks; wherein each block corresponds to a terminal equipment, and a starting position and/or size of each block is/are configured by high-layer signaling, wherein each block includes one or more bits, indicating an index of the switched BWP of the terminal equipment.
For example, still by taking the bitmap of multiple blocks shown in
For example, in a case where each block correspondingly opens or closes at least some of spatial elements, the terminal equipment is about to switch an index of a BWP, for example each block includes X bits corresponding to an index of a BWP. In some implementations, for settings of a BWP and its index, related arts may be referred to, the present disclosure does not make limitations in this regard.
For example, a terminal equipment is configured with four BWPs, indication information indicates a switched BWP index via two bits, for example “00” represents switching to BWP 0, “01” represents switching to BWP 1, “10” represents switching to BWP 2, and “11” represents switching to BWP 3. For example, higher-layer signaling configures BWP 0 to be associated with CSI 0, BWP 1 to be associated with CSI 1. After the service mode is changed to the power-saving mode, for example the indication information indicates “00”, correspondingly activates CSI 0 and deactivates CSI report of the terminal equipment in a normal mode, for example deactivates CSI 1 in the normal mode and configured by higher-layer signaling.
For example, for two terminal equipments, in a case where the service mode is changed, the indication information is “‘10’ ‘01’”; by taking a first terminal equipment as an example, the indication information obtained by the first terminal equipment via higher-layer signaling is 4 bits in total, wherein a size of each block is 2 bits, and the first to second bits are indication bits of the first terminal equipment, wherein ‘10’ indicates switching to BWP 2 for the first terminal equipment.
In some implementations, if a BWP of the terminal equipment needs to be switched, the indication information carries a corresponding block of the terminal equipment; and if a BWP of the terminal equipment does not need to be switched, the indication information does not carry the corresponding block of the terminal equipment. For example, if the terminal equipment fails to read relevant fields of the indication information via higher-layer signaling, it is considered that a BWP of the terminal equipment does not need to be switched.
In some implementations, the terminal equipment suspends a BWP index before the service mode is changed; and after the first timer expires, the terminal equipment resumes the BWP index before the service mode is changed.
For example, the network device transmits the configuration information via higher-layer signaling, such as RRC signaling, wherein the configuration information indicates an application time of the power-saving mode. For example, after reading RRC signaling, the terminal equipment obtains the application time of the energy-saving mode, the network device changes a service mode (for example, from the normal mode to the energy-saving mode) and transmits indication information to the terminal equipment (using said indication method), the terminal equipment switches a BWP index and suspends a BWP index in the normal mode, and resumes the normal mode after 300 ms, i.e., the first timer expires, and switches back to the BWP index in the normal mode.
Thus, the terminal equipment may obtain specific content of the indication information, and may determine a switched BWP index.
